28. Omarion "O" (2005)
Make fun of Omarion all you want. (We will.) But playing this song ahead of lovemaking is like finding an incredible treasure behind a heavy door by using a secret key that you want to tell all of your friends about, but then you remember that the key is Omarion so you just keep your mouth shut and never tell anyone about the key or the door or anything in general ever again.
